The police have identified all nine victims of the helicopter crash that killed Kobe Bryant and his daughter Gianna.

As previously reported, the retired NBA star was killed in a fatal crash in Calabasas, California, Sunday (January 26). He had been traveling with eight other people in his private helicopter at the time. According to The New York Times, the group was on their way to basketball practice at Mamba Sports Academy in Thousand Oaks.

Among those killed were friends of Gianna, parents, coaches and a pilot.
